Description

Technical Field

[0001] The utility model relates to the field of greenhouse breeding, in particular to an agricultural greenhouse used for breeding black-spotted frogs. Background Art

[0002] The black-spotted frog (Pelophylax nigromaculatus) is also called the black-spotted frog. Artificially bred black-spotted frogs are cultured in small ponds with high density. They are usually bred in rivers, ponds, and grasses near flowing water. Through the influence of the natural environment, black-spotted frogs can pair up, lay eggs, and hatch on their own. This is an ecological and efficient new breeding model. However, this type of breeding technology is easily affected by the external environment (such as temperature, light, water quality, humidity, etc.). Especially during the summer and winter seasons, the breeding and management of black-spotted frogs in extreme weather conditions of high temperature and cold is very difficult.

[0003] The prior art usually sets up a greenhouse in the breeding environment, and uses the greenhouse to protect the breeding environment of the black-spotted frog from high temperature, low temperature or direct sunlight. However, when the existing greenhouse encounters different external environmental conditions of high temperature or low temperature and needs to be adjusted, it is usually judged manually based on experience whether to adjust. This may easily lead to failure to adjust and switch in time, causing drastic changes in the environment in the greenhouse, which is not conducive to the growth of the black-spotted frog. In addition, it is necessary to manually switch the ventilation holes of the greenhouse to open or close, which threatens the safety of personnel in bad weather. The prior art adjusts the ventilation and temperature in the greenhouse by setting a winch to cooperate with the pipe rack winch to switch the film on the side or top of the greenhouse to be gathered or unfolded; however, when the greenhouse is long and the span is large, the use of a single-sided winch is prone to the center of the pipe rack and the symmetrical side of the winch falling, and the pipe rack cannot rotate evenly. When the tarpaulin on the side of the greenhouse is gathered, the tarpaulin is unevenly stressed, resulting in a short life of the tarpaulin and high pressure on the single-sided winch; if winches are set on both sides, the two winches are prone to synchronization incoordination, and even the hoisting directions on both sides are opposite, resulting in damage to the pipe rack and the winch. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the utility model provides an agricultural greenhouse for breeding black-spotted frogs which is convenient for gathering rolling curtains under a large span.

[0017] The cavity is provided so that the excess rope of the traction rope can be stored without cutting, and the traction rope can be conveniently adjusted according to the position of the traction rope tightening assembly so that the forces exerted by the two traction ropes on the two ends of the winding rod are kept consistent.

[0018] Furthermore, two limiting rings are symmetrically arranged on the annular wall of the disc body, and the traction rope is located between the two limiting rings when it is gathered.

[0020] The beneficial effects of the utility model are:

[0021] The utility model provides a winding tube assembly and a traction rope gathering assembly at both ends of the winding rod. The traction rope gathering assembly can be used to pull up both ends of the winding rod at the same time. While pulling up, the winding rod is rotated under the action of the gear and the rack to drive the rolling curtain cloth to be gathered. During the whole process, the rotational force and the upward pulling force at both ends of the winding rod are balanced, and the winding rod will not fall unilaterally to cause uneven mechanical force, thereby increasing the entire service life.
